Well, we don't want to use ctime because it is not thread-safe.
glibc ctime_r implementation should be safe if the passed buffer is at least 26
bytes long, it calls internally asctime, which is:
/* Like asctime, but write result to the user supplied buffer.  The
   buffer is only guaranteed to be 26 bytes in length.  */
char *
__asctime_r (const struct tm *tp, char *buf)
{
  return asctime_internal (tp, buf, 26);
}
and asctime_internal uses the passed buflen as second argument to snprintf.
